install–38 - Ibm

esponses from every IP address in the subnet,
especially for IP addresses where no devices are
present. There might, however, be times when a full
subnet sweep will produce valuable diagnostic
information about the network or a device’s
configuration.
switch. A fibre channel device that provides full
bandwidth per port and high-speed routing of data by
using link-level addressing.
switch group. A switch and the collection of devices
connected to it that are not in other groups. Switch
Groups are discovered by the SANavigator tool and
displayed with a gray background on the Physical and
Data Path Maps.
system name. Device name assigned by the vendor’s
third-party software.
TCP. See Transmission Control Protocol.
TCP/IP. See Transmission Control Protocol/Internet
Protocol.
terminate and stay resident program (TSR
program). A program that installs part of itself as an
extension of DOS when it is executed.
TFT. See thin-film transistor.
thin-film transistor (TFT). A transistor created by
using thin film methodology.
topology. The physical or logical arrangement of
devices on a network. The three fibre channel
topologies are fabric, arbitrated loop, and point-to-point.
The default topology for the disk array is arbitrated loop.
TL_Ports. See translated loop port.
translated loop ports (TL_Ports). Each TL_Port
connects to a private loop and allows connectivity
between the private loop devices and off loop devices
(devices not connected to that particular TL_Port).
Transmission Control Protocol (TCP). A
communication protocol used in the Internet and in any
network that follows the Internet Engineering Task Force
(IETF) standards for internetwork protocol. TCP
provides a reliable host-to-host protocol between hosts
in packed-switched communication networks and in
interconnected systems of such networks. It uses the
Internet Protocol (IP) as the underlying protocol.
Transmission Control Protocol/Internet Protocol
(TCP/IP). A set of communication protocols that
provide peer-to-peer connectivity functions for both local
and wide-area networks.
trap. In the Simple Network Management Protocol
(SNMP), a message sent by a managed node (agent
function) to a management station to report an
exception condition.
trap recipient. Receiver of a forwarded SNMP trap.
Specifically, a trap receiver is defined by an IP address
and port to which traps are sent. Presumably, the actual
recipient is a software application running at the IP
address and listening to the port.
TSR program. See terminate and stay resident
program.
user action events. Actions that the user takes, such
as changes in the SAN, changed settings, and so on.
Each such action is considered a User Action Event.
vendor. Property value that the SANavigator tool uses
to launch third-party software. Vendor property might be
discovered but will always remain editable.
VGA. See video graphics adapter.
video graphics adapter (VGA). A computer adapter
that provides high-resolution graphics and a total of 256
colors.
video random access memory (VRAM). A special
type of dynamic RAM (DRAM) used in high-speed video
applications, designed for storing the image to be
displayed on a computer’s monitor.
VRAM. See video random access memory.
WORM. See write-once read-many.
Worldwide Name (WWN). A registered, unique 64–bit
identifier assigned to nodes and ports.
write-once read-many (WORM). Any type of storage
medium to which data can be written only a single time,
but can be read from any number of times. After the
data is recorded, it cannot be altered. Typically the
storage medium is an optical disk whose surface is
permanently etched by using a laser in order to record
information. WORM media are high-capacity storage
devices and have a significantly longer shelf life than
magnetic media.
WWN. See worldwide name.
XGA. See eXtended graphics array.
zoning. A function that allows segmentation of nodes
by address, name, or physical port and is provided by
fabric switches or hubs.
